solution. Compared to a 60m airline link between rig
and compressor, direct flow because of the on-board
compressor requires a much smaller compressor to get
the job done. It also eliminates the need for hauling the
compressor around behind a tow vehicle. This complete
system now only has two engines – the excavator and the
compressor – reducing fuel consumption, maintenance
and repairs.
The drilling machine is also fitted with two separate
independent fire suppression systems supplied by
Integrated Air Solutions. Suitable for any engine
compartment, this triple action system from Fogmaker,
Sweden, attacks all three components in the fire triangle
– heat, oxygen and fuel. Using high-pressure water
mist (50-micron droplets) the system can supress and
extinguish engine and hydraulic compartment fires in
10 seconds with only water, and 3% AFFF and cool down
the compartment to prevent re-ignition. With no powder
or mess, clean-up is fast and easy, minimising downtime.
After a discharge, it’s a simple matter of replacing the
detector hose and refilling the piston accumulator and the
system is ready to go.
More add-ons
The conversion of the JS205 also included the
incorporation of a few additional buttons on the joystick
so that all functions can be seamlessly controlled from
inside the cabin, putting the operator in complete control.
Another important safety feature is the inclusion of a
dead man switch that puts the machine into limp mode in
the event of a problem.
A second JS205 drilling machine has already been
manufactured and according to Roelofse a third unit will
be ready in March 2018.
“We keep it simple with accessible parts and
quick easy and maintenance, so that the machine is
the ideal workhorse for drilling applications on the
African continent,” says Reolofse. Kemach Equipment
has dedicated one person to site and Integrated Air
Solutions has appointed a mechanic to support the
Liyema Drilling team. ■
